Havre's Wastewater Woes Solved By Beer

Upcycling spent barley helps to ease wastewater treatment. In Havre, Montana, the town’s wastewater treatment plant uses barley from a local brewery, Triple Dog Brewing, to feed bacteria. The nutrients from the barley give the bacteria a boost, helping to reduce nitrogen and phosphorous levels in the water. The collaboration means that Havre can save on expensive solutions and upgrades to its wastewater treatment plant.
